1. A data transmission method, comprising: segmenting or concatenating, by a sending device, data packets of a first service to be transmitted to a same receiving device, so as to generate a plurality of segments of data packets; for multiple radio access technologies, packaging and numbering, by the sending device, the plurality of segments of data packets, wherein the multiple radio access technologies adopt an aggregation mode, and the aggregation mode indicates a mode in which different radio access technologies are used to transmit different contents; and sending, by the sending device, the packaged data packets to the receiving device by using corresponding radio access technologies according to the numbers; wherein the multiple radio access technologies comprise a first radio access technology and a second radio access technology, the plurality of segments of data packets comprise a first segment of data packets and a second segment of data packets, and the first segment of data packets and the second segment of data packets are respectively transmitted in the aggregation mode by using the first radio access technology and the second radio access technology.
This invention relates to data transmission methods for improving efficiency and reliability in wireless communication systems using multiple radio access technologies (RATs). The problem addressed is the need to optimize data transmission across heterogeneous networks, such as combining cellular (e.g., 5G) and Wi-Fi, to leverage the strengths of each technology while ensuring seamless delivery. The method involves a sending device processing data packets of a service destined for a single receiving device. The device segments or concatenates the data packets into multiple segments. These segments are then packaged and numbered for transmission over different RATs operating in an aggregation mode. The aggregation mode allows different RATs to transmit different segments of the data, enabling parallel transmission and load balancing. For example, a first segment of data packets is transmitted via a first RAT (e.g., 5G), while a second segment is transmitted via a second RAT (e.g., Wi-Fi). The receiving device reassembles the segments based on the numbering to reconstruct the original data. This approach enhances throughput, reduces latency, and improves reliability by utilizing the best available RAT for each segment. The method is particularly useful in scenarios where multiple RATs are available, such as in multi-RAT devices or heterogeneous networks.
2. The method according to claim 1 , wherein the multiple radio access technologies adopt a diversity mode and the aggregation mode, and the diversity mode indicates a mode in which different radio access technologies are used to transmit the same content.
This invention relates to wireless communication systems that utilize multiple radio access technologies (RATs) to improve data transmission reliability and efficiency. The problem addressed is the need for flexible and efficient use of diverse RATs to enhance communication performance, particularly in scenarios where signal quality or network conditions vary. The method involves operating in two distinct modes: a diversity mode and an aggregation mode. In the diversity mode, different RATs are used to transmit the same content, ensuring redundancy and improving reliability. This is particularly useful in environments where one RAT may experience interference or signal degradation, as the redundant transmission via another RAT ensures data integrity. The aggregation mode, on the other hand, combines multiple RATs to increase the overall data throughput by leveraging the combined bandwidth and capabilities of the available technologies. The system dynamically selects between these modes based on network conditions, user requirements, or other performance metrics. By intelligently switching between diversity and aggregation, the method optimizes both reliability and efficiency, adapting to changing communication environments. This approach is beneficial in heterogeneous networks where multiple RATs, such as 4G, 5G, Wi-Fi, or other wireless standards, coexist and can be utilized synergistically.
3. The method according to claim 2 , wherein the plurality of segments of data packets comprise a first segment of data packets, a second segment of data packets and a third segment of data packets, the first segment of data packets is transmitted in the diversity mode, and the second segment of data packets and the third segment of data packets are respectively transmitted in the aggregation mode.
In wireless communication systems, efficient data transmission is critical to maintaining reliable connectivity, especially in environments with interference or signal degradation. A method for transmitting data packets improves reliability by combining diversity and aggregation techniques. The method involves dividing data packets into multiple segments, including a first segment, a second segment, and a third segment. The first segment is transmitted using a diversity mode, where redundant copies of the data are sent over different channels or paths to enhance reception reliability. The second and third segments are transmitted using an aggregation mode, where data is split across multiple channels or paths to increase throughput. By selectively applying diversity to the first segment and aggregation to the subsequent segments, the method balances reliability and efficiency. This approach ensures critical data is protected against errors while optimizing overall transmission speed. The technique is particularly useful in scenarios where both robustness and high data rates are required, such as in mobile networks or IoT applications.

This invention relates to wireless communication systems where a sending device uses multiple radio access technologies (RATs) to improve data transmission reliability and efficiency. The problem addressed is ensuring robust and efficient data delivery in environments with varying network conditions by leveraging different RATs. The sending device supports both diversity and aggregation modes. In diversity mode, the same content is transmitted simultaneously or redundantly over different RATs, enhancing reliability by providing alternative paths if one RAT fails or degrades.

The device dynamically selects between these modes based on network conditions, user requirements, or application needs. For example, in high-priority or critical communications, diversity mode ensures redundancy, while aggregation mode is used for high-throughput applications. The system may also prioritize certain RATs based on signal strength, latency, or cost considerations. This approach improves overall communication resilience and performance by adaptively utilizing available RATs, making it suitable for applications requiring both reliability and high data rates.

The invention optimizes this trade-off by segmenting data packets into distinct groups for different transmission modes. The system involves a sending device that divides data packets into three segments: a first segment transmitted in diversity mode, and second and third segments transmitted in aggregation mode. The diversity mode ensures critical data is reliably received, while the aggregation mode maximizes throughput for less critical data. This hybrid approach adapts to channel conditions, improving overall performance. The sending device may also adjust transmission parameters, such as modulation schemes or coding rates, based on feedback from the receiving device to further optimize transmission efficiency.
